Orange wheat blossom midge larvae feed on developing grains. The larvae produced by the orange wheat blossom midge can cause grains to become small and shrivelled. They can also damage the outer grain layer (pericarp) which allows water to enter. This results in grain which becomes vulnerable to fungal infection and premature sprouting. Control with help of DSS on platform.ipmdecisions.net The susceptible crops are at highest risk when adult midge emergence coincides with ear emergence, particularly at growth stages between 53 and 59. The model predicts the emergence of adults and associated migration of females into vulnerable crops and when increased monitoring and/or treatment may be appropriate. The model uses daily temperature (degree Celsius) and rainfall (mm) to identify the emergence of Orange Wheat Blossom Midge. It runs between the months May and June, but requires weather data from the 1st of January. The DSS output show that the risk of emergence of orange wheat blossom midge and migration into crops is increasing. Suitable rainfall events have taken place, and/or daily temperatures are suitable for orange wheat blossom midge emergence which is visualised as a red line in the risk status diagram. This means that increased monitoring efforts or treatments may be appropriate. This DSS was adapted from work carried out in Belgium, and is considered to be applicable, but yet to be validated in the UK, Luxembourg, Netherlands, France, Germany and Denmark.

Agricultural run-off and subsurface drainage tiles transport a significant amount of nitrogen and phosphorus leached after fertilization. alchemia-nova GmbH in collaboration with University of Natural Resources and Life Sciences, Vienna developed two multi-layer vertical filter systems to address the agricultural run-off issue, which has been installed on the slope of an agricultural field in Mistelbach, Austria. While another multi-layer addressing subsurface drainage water is implemented in Gleisdorf, Austria. The goal is to develop a drainage filter system to retain water and nutrients. Both multi-layer filter systems contain biochar and other substrates with adsorption properties of nutrients (nitrogen, phosphorus). The filter system can be of practical use if an excess of nutrients being washed out is of concern in the fields of the practitioner by keeping the surrounding waters clean. This approach may result in economic value by re-using the saturated biochar as fertilizer and improving the soil structure, thus increasing long-term soil fertility.

FACTSHEET NANOCELLULOSE MEMBRANES FOR NUTRIENT RECOVERY Key information Functionalized nanocellulose membranes can take up nitrate and phosphate. These membranes can be put in a water treatment unit. As the membranes are biobased, degradable materials, they can after use be added to the soil, thus returning the leached nutrients back for their original purpose providing fertilizers (nutrient recycling).
Because variables such as temperature and humidity have a profound effect on the activity of crop pests, diseases and natural enemies, the ability to monitor environmental conditions within a crop has always been important for crop protection.
